On platforms with HAVE_PCI_MMAP or ARCH_GENERIC_PCI_MMAP_RESOURCE, resource files are now handled by static attribute groups registered via pci_dev_groups[]. Stub out the pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files(), as the dynamic resource file creation is no longer needed. Also, simplify pci_sysfs_init() on these platforms to only iterate buses for legacy attributes creation, skipping the per-device loop. Move the __weak stubs for pci_create_resource_files() and pci_remove_resource_files() into the #else branch since only platforms without HAVE_PCI_MMAP (such as Alpha architecture) still need them. Guard the res_attr[] and res_attr_wc[] fields in struct pci_dev the same way.
